Cannibalism appears again and again in the human record. The oldest clear case is Homo antecessor at Gran Dolina ~800,000 years ago; Neanderthals and even Ice Age modern humans did it too. Whether for survival, ritual or defence is still debated.
It is one of the most uncomfortable findings in archaeology: our ancestors and cousins sometimes ate one another. And it is not a rare aberration. The signs of cannibalism — human bones butchered exactly like animal prey — turn up across hundreds of thousands of years of the human story.
How do we know it was cannibalism?
Archaeologists look for a specific signature: stone-tool cut marks where muscle was sliced from bone, percussion damage from smashing bones open for marrow, and human remains discarded in the same way, in the same place, as butchered animals. When human bones show the full ‘butchery package’ and are mixed with food refuse, the conclusion is hard to avoid.
Gran Dolina: the oldest case
The earliest well-documented example comes from Gran Dolina in the Sierra de Atapuerca, Spain, where Homo antecessor lived around 800,000 years ago. Many of the human bones there — mostly from children and adolescents — carry cut marks and breakage identical to the deer and horse bones beside them. Researchers read this as ‘nutritional cannibalism’, possibly directed at outsiders, making it the oldest known cannibalism in Europe.
Neanderthal cannibalism
The pattern recurs among Neanderthals. At Moula-Guercy and Les Pradelles in France, at El Sidrón in Spain and Goyet in Belgium, Neanderthal bones were defleshed and cracked for marrow. At El Sidrón an entire family group seems to have been eaten — perhaps a sign of starvation in hard times.
Ice Age skull-cups
Even early modern humans did it. At Gough’s Cave in England, ~14,700-year-old Homo sapiens remains were butchered, and some skulls were carefully shaped into drinking cups — a hint that here the practice was as much ritual as nutrition.
Why did they do it?
There is no single answer. Some cases look like survival cannibalism in famine; others like violence between groups; others like funerary ritual. The one certainty is that eating the dead — for food or for meaning — is a deeply ancient part of the human repertoire.
Why it matters
Cannibalism forces us to see our extinct relatives as fully human in their complexity — capable of the same range of desperate, violent and symbolic behaviour as us. It also warns against tidy stories: the same cut marks can mean starvation in one cave and reverence in another.

What is the oldest evidence of cannibalism?
The oldest well-documented case is Homo antecessor at Gran Dolina in Spain, around 800,000 years ago, where human bones — mostly of children — were butchered and discarded like animal food remains.
Did Neanderthals practise cannibalism?
Yes, at several sites including Moula-Guercy, El Sidrón and Goyet, Neanderthal bones show cut marks and marrow extraction. It may reflect starvation, violence between groups, or ritual, depending on the site.
Why did early humans eat each other?
Reasons varied: survival during famine, warfare or defence against outsiders, and funerary ritual. At Gough's Cave, modern humans even shaped skulls into cups, suggesting symbolic rather than purely nutritional motives.
